9 out of 10 stars?...
I noticed the first review on the front page by a Simon Richardson who gives this movie a 9/10. I smell a rat.
I watched this movie with friends the other night, they were looking forward to watching it since it had "scariest movie of the year" on the back of the DVD. I was a little bit cynical being a (good) horror movie buff and after I watched it I was right.
Boo just seemed to drag on too much and was too long for 97 minutes, the film makers just wanted to give us gore and not create any atmosphere.
It just didn't work.
